Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Die einzige zur Beschreibung gehörende Figur zeigt in einer Teilansicht eines Kraftfahrzeugs den Bereich eines Frontscheinwerfers.An embodiment of the invention is shown in the drawing and explained in more detail in the following description. The only figure belonging to the description shows in a partial view of a motor vehicle the area of a headlight.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Einem zu einem Kraftfahrzeug gehörenden Frontscheinwerfer 10 ist eine die Scheinwerfer-Abdeckscheibe 12 reinigende Wischvorrichtung zugeordnet. Die Wischvorrichtung weist einen Wischerarm 14 auf, an dessen freien Ende ein Wischblatt 16 befestigt ist. Der Wischerarm 14 ist derart abgewinkelt, daß das Wischblatt 16, zusammen mit dem freien Ende des Wischerarms 14, in der in der Zeichnung dargestellten Ablagestellung des Wischers 14, 16 am unteren Rand der Abdeckscheibe 12 abgelegt ist. Unterhalb der Abdeckscheibe 12 ist die Fahrzeugkarosserie 17 mit einem Bauteil 18 versehen, dessen Höhe, von der Scheibe 12 aus gemessen, der Gesamtbauhöhe des Wischers 14, 16 angepaßt ist. Das Bauteil 18 weist eine zur Scheibe 12 hin offene, nischenförmige Aussparung 20 auf, welche den Wischer 14, 16 in seiner Ablagestellung aufnimmt. Die Nische 20 ist in Anlaufrichtung (Pfeil 21) offen, so daß der Wischer 14, 16 aus dieser heraus anlaufen und im Pendelbetrieb arbeiten kann. Das Bauteil 18 bildet also einegegenüber der Scheibe 12 vorspringende Stufe, die bis an die in Ablagestellung befindlichen Teile 14, 16 der Wischvorrichtung heranreicht. Die Tiefe der Nische 20 - gemessen in Bewegungsrichtung des Wischers 14, 16 - ist der Breite des Wischblatts 16 bzw. der Breite des Wischerarms 14 angepaßt. Weiter bildet die Nische noch einen Freiraum 22, der einen Pendelbetrieb des Wischerarms 14 ermöglicht. Die Nische 20 ist so ausgebildet, daß das von dem Wischerarm 14 abgewandte Ende des Wischblatts 16 von einer Schulter 24 abgedeckt ist. In dem, bezogen auf das Wischblatt hinter der Schulter 24 liegenden Abschnitt des Bauteils 18, ist eine auf die zu wischende Scheibe 12 gerichtete Spritzdüse 26 für Waschflüssigkeit angeordnet. Das Bauteil 18 ist aus Kunststoff gefertigt und schalenförmig ausgebildet. Es weist an seiner Frontseite Rippen 30 auf, die sich optisch vorteilhaft auswirken, so daß eine saubere Integration des Bauteils 18 in die Fahrzeugkarosserie 17 möglich ist.A headlight 10 belonging to a motor vehicle is assigned a wiper device which cleans the headlight cover plate 12. The wiper device has a wiper arm 14, on the free end of which a wiper blade 16 is fastened. The wiper arm 14 is angled such that the wiper blade 16, together with the free end of the wiper arm 14, is placed in the storage position of the wiper 14, 16 shown in the drawing on the lower edge of the cover plate 12. Below the cover plate 12, the vehicle body 17 is provided with a component 18, the height of which, measured from the plate 12, is adapted to the overall height of the wiper 14, 16. Component 18 has a niche-shaped cutout 20 which is open towards window 12 and which receives wiper 14, 16 in its storage position. The niche 20 is open in the start-up direction (arrow 21), so that the wiper 14, 16 can run out of it and work in the shuttle mode. The component 18 thus forms a step projecting with respect to the pane 12, which reaches as far as the parts 14, 16 of the wiper device which are in the storage position. The Depth of the recess 20 - measured in the direction of movement of the wiper 14, 16 - is adapted to the width of the wiper blade 16 b between the width of the wiper arm 14. The niche also forms a free space 22 which enables the wiper arm 14 to operate in a pendulum manner. The recess 20 is designed such that the end of the wiper blade 16 facing away from the wiper arm 14 is covered by a shoulder 24. In the section of the component 18 which is located behind the shoulder 24 with respect to the wiper blade, a spray nozzle 26 for washing liquid is arranged which is directed towards the window 12 to be wiped. The component 18 is made of plastic and has a bowl-shaped design. It has ribs 30 on its front side which have a visually advantageous effect, so that a clean integration of the component 18 into the vehicle body 17 is possible.

Gemäß einer Hieht dargestellten Weiterbildung der Erfindung kann das Bauteil 18 im Bereich der Ablagenische 20 mit einer den Wischerarm und das Wischblatt abdeckende Platte versehen sein, so daß sich ein Ablageschacht für den Wischerarm 14 und das Wischblatt 16 ergibt. In diesem Fall ist der Wischer 14, 16 in seiner Ablagestellung nicht sichtbar.According to a further development of the invention, the component 18 can be provided in the area of the storage niches 20 with a plate covering the wiper arm and the wiper blade, so that there is a storage shaft for the wiper arm 14 and the wiper blade 16. In this case, the wiper 14, 16 is not visible in its storage position.

Beiden Ausführungen ist jedoch gemeinsam, daß durch die Anordnung des erfindungsgemäßen Bauteils 18 ein Schutz der über die Abdeckscheibe 12 bewegbaren Wischerteile 14, 16 bewirkt wird. Wie aus der Figur leicht ersichtlich ist, weist das erfindungsgemäße Kraftfahrzeug im Bereich seiner Wischvorrichtung keine Angriffspunkte auf, an denen beispielsweise Reinigungsbürsten von automatisch arbeitenden Fahrzeugwäschanlagen angreifen und die Wischerteile beschädigen können.However, both versions have in common that the arrangement of the component 18 according to the invention provides protection for the wiper parts 14, 16 which can be moved over the cover plate 12. As can easily be seen from the figure, the motor vehicle according to the invention does not have any points of attack in the area of its wiper device, at which, for example, cleaning brushes of automatically operating vehicle washing systems attack and can damage the wiper parts.
